CAML query not filtering results

Question

Can someone tell me why the following CAML query is not filtering results? It's returning files that do not contain "/Internal/Bug 594" in their FileRef value. Thanks.

<View Scope='Recursive'>
    <RowLimit>1000</RowLimit>
    <Query>
        <And>
            <Eq>
                <FieldRef Name='FSObjType' />
                <Value Type='Text'>0</Value>
            </Eq>
            <Contains>
                <FieldRef Name='FileRef' />
                <Value Type='Text'>/Internal/Bug 594</Value>
            </Contains>
        </And>
    </Query>
</View>

And here's the code i'm using to execute this query:

CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml = [the query you see above];

//IEnumerator<ClientOM.List> LibsIterate = null;
ListItemCollection tempItems = LibsIterate.Current.GetItems(camlQuery);

//ClientOM.ClientContext clientContext = null;
clientContext.Load(tempItems);
clientContext.ExecuteQuery();

//List<ListItem> allItems = new List<ListItem>();
allItems.AddRange(tempItems.ToList());

I think the problem is that the value of the FileRef field contains a space. Try replacing the space with %20 and see if it works.
